Surprise pregnancy and partners

My fiancé and I hadn't yet decided if we'd have more kids. Last we talked about it he was no where near ready and wanted to wait a year or two 
(We both have children from previous relationships-this baby will be #5)
We were using condoms amd pull out and I got pregnant. He is having a hard time. It's really depressing to be excited to get to have 1 last baby and not have my partner share in my excitement. He found out Mother's Day and he says he just needs time to process but he still says stuff like "I don't want a baby right now" and it's really sad 😢
Anyone else in this boat?
